TAPPING DEVICE.

To all whom t may concern Be it known that l, O'RLIN H. HINMAN, acitizen of the United States, and a resident of Kensington, in thecounty of Smith and State of Kansas, have invented a new and ImprovedTapping Device, of which the following is a full, clear, and exactdescription.

My invention has for its object to provide an inexpensive device fortapping a pipe containing a fluid, under pressure, without the loss ofthe fluid, and where the pipes are too thin for cutting threadedopenings therein.

The device is constructed with a pipe saddle, connected with a memberhaving a drill chamber by valve, a drill extending into the drillchamber through a packing member', and through openings in the valve andsaddle member, so that when an opening has been drilled in the pipe, thedrill may be raised therefrom, without danger of the escape of thefluid, it being possible to turn the valve when the drill is raisedthereabove, so that the member having the drill chamber may be removedwith the drill. `When the member having the drill chamber has beenremoved, a pipe may be connected with the valve to direct the fluid fromthe main pipe when the valve is again opened.

Another object of the invention is to provide simple and convenientmeans for operating the drill.

Still other objects of the invention will appear in the followingcomplete specification, in which the preferred form of the invention isdisclosed.

Tn the drawings similar characters of reference indicate correspondingparts in all the views, in which- Figure 1 is a view showing my tappingdevice in position for use; Fig. 2 is a sectional view on the line 2 2of Fig. 3; Fig. 3 is a sectional view on the line 3 3 of Fig. 2; andFig. l is a fragmentary sectional view, on the line 4 4 of Fig. 1,showing how a brace is used with the tapping device.

By referring to the drawings it will be seen that on the main pipe 5,there is adjusted the pipe saddle 6, consisting of the U-shaped member7, which extends under the main pipe 5, this U-shaped member 7 havingterminals 8, which extend up through openings 9 in a saddle member 10,the saddle member 10 being separated from the main pipe 5 by a gasket11. The saddle Specification of Letters Patent.

Application filed October 18, 1912.

Patented June 17, 1,913. Serial No. 726,420.

member 10 is held in position by the nuts 12, which mesh with thethreads 13 on the terminals 8 of the U-shaped member 7, these nuts 12pressing against the upper surface of the saddle member l0. It willtherefore be seen that the gasket 11 will be held snugly between themain pipe 5 and the saddle member 10, so that when a hole is drilledthrough the gasket 11 in the main pipe 5, the gasket 11 will be disposedaround this opening, and will prevent the leakage of the liuid containedin the main pipe 5, around the drill hole.

The saddle member 10 has a threaded opening 111, extending from itsupper surface down to the gasket 1l, and meshing in this threadedo-pening 14 there is a threaded projection 15 of a valve 16. This valve1G has an outer thread 17 on a projecting portion 18, by which means itis secured to the member 19 having the drill chamber 20. This member 19has a similar thread 21, the threads 17 and 21 being engaged by athreaded coupling member 22 for holding the member 19 in position abovethe valve 1G. Tt will be noticed that the openings in the saddle member10 and the valve 1G form a continuation of the drill chamber 20, so thata drill 23 disposed in the drill chamber 2O may extend through theopenings in the valve and down to the gasket 11, so that when the drill23 is rotated it will drill a hole through the gasket 11, and throughthat portion of the main pipe 5 adjacent thereto. One of the objects ofthe invention is to prevent the escape of a liuid under pressure in themain pipe 5, when an opening in the main pipe 5 has been drilled, and asthe fluid will flow around the drll 23, as soon as it penetrates themain pipe 5, T provide means for preventing the escape of the fluid fromthe drill chamber 20. This means consists of a member 24 having a thread25, meshing with a thread 2G at the upper terminal of the member 19,this member 24- having an openino' 27, through which the drill 24 isdisposed, there being a packing cavity 28 in the member 24- around thedrill 27, in which is disposed a packing 29, which is pressed downwardand against the drill .23 by means of the packing nut 30, which has anouter thread 31 meshing with the inner thread 32 in the packing cavity2S. The packing nut 30 has an opening 33, through which the drill 23extends. Tt will therefore be seen that when the drill 23 penetrates themain pipe 5 the water will be prevented from escaping from the member19. When the hole has been drilled in the main pipe, the drill 23 may beraised above the valve 1G, when the valve 16 may be turned, after whichthe member 19 may be freed by loosening the coupling nut 22. lllhen thishas been done the member l5), with the drill 23, may be removed, and apipe may be connected with the projecting portion 18 of the valve 1G, toreceive and direct the fluid when the valve 1G is again opened.

As a convenient, simple and inexpensive means for operating the drill, Iprovide a brace 3st, `having a threaded member 35, Awhich is disposedthrough an opening in a flange plate 3G, `this flange plate 36 beingheld in position by a nut 37, which meshes with a thread on the threadedmember, the

lflange plate 3G being connected with the flan ge 38 on the member lf),by means of the chain 39, which extends through the openings 40 in theflange 3S, and through similar openings in the flangeplate 36. It willbe seen that when the upper terminal 1li. of t-he drill is connectedwith the member' 42 of the brace 84s, the chain 39 may be adjusted t-ohold the flange plate 3G down in the direction of the flange 8S, bywhich means the drill may be pressed downward, as the brace 34 isoperated.

I-Iaving thus described my invention, I claim as new and desire tosecure by Letters Patent:

l. In a tapping device, a member having a drill chamber and an outwardlyextending flange, a brace having a flange plate, means connecting the Vflange and flange plate to limit the movement of the brace away from themember having the drill chamber, and a drill extending into the drillchamber and connected with the brace to be operated thereby.

2. In a tapping device, a pipe saddle having an opening, a valve securedto the pipe middle and having an opening connected with the firstopening, a member having a drill chamber secured to the valve with itschamber in communication with the opening in the valve, a drillextending into the drill chamber and adapted to extend through theopenings in the valve and in the pipe saddle, and a flange on themember, a brace having a flange plate, means connecting the flange andflange plate to limit the movement of the brace away from the drillchamber, and means connecting the brace with the drill for operating thelatter.

3. In a tapping device, a member having a drill chamber and a flange, abrace having a threaded member, a flange plate having an opening throughwhich the threaded member extends, a nut on the threaded member forpressing against the flange plate to move the flange into desiredposition, means connecting the flange and flange plate to limit themovement of the brace away from the member having the drill chamber,vand a drill extending .into tbe drill chamber and connectedA with thebrace to be operated thereby.

t. In a tapping device, a member having a drill chamber and a flange, abrace, a flange plate, means by which the last-mea tioned flange may beadjusted and held in position relatively to the brace, means connectingthe flange and flange plate to limit the n'iovement of the brace awayfrom the member having the drill chamber, and a drill extending into thedrill chamber and connected with the brace to be operated thereby.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
